THBEADING ATTACHMENT Ton sH TTLEs or Looms.

"To aZZwh'om it may concern Beit known that 1, JOHN W. SMALL, a citizen of the United States,'resi ding at Burlington, in the county of Alamance and new and useful Threading Attachment for Shuttles of Looms, of which is a specification. 1

attachments for shuttles of looms and its object is to provide an easily" applied attachment readily adaptable to existing shuttles, whereby the shuttle may. be threaded with a minimumof' effort andwithout liwi bility ofputting the thread und'e'r undue strain in either threading or in the opera- 'tion of the shuttle.

In accordance .with the inventionth'e shut-j tle may be of customary form with a central cavity to carry the usual'bobbin; and .one end of the cavity is covered by a plate in turn supported by a post or leg made fastat convenient points tothe shuttle, and ten.- slon means are provided,

an eye guiding the thread as the shuttle 'moves back and forth in'its course.

The inventionis restrictedj'to' the devices or structures by means of which the thread is supported and tensioned inpassing from the bobbin to the'material being woven The invention will be best understood from a consideration ofthe following de-;

tailed description taken in connection with the accompanying I drawings 'forming' part a of this specification; with the understanding,

however, that the invention is not confined to any strict conformity with the showing in the drawings, but maybe changed and" igure 1 isa'plan view of the shuttle.

from which the thread emerges. State ofNorth. Carolina, have invented a r the following: p 't1on,' and theshuttle is 's'hown as provided This invention has referenceto threadlng around and through which the thread is carried to ultiv matelyleave one side of the shuttle through line as of Fig. 5 is-a section on the linev of F1g.-l. i

Fig. 6 is a detailed View of the eye plate Referring to the drawings there is shown and consequentlyrequires no specialdescripwith a bobbin 2 and thread 3'thereon, as is customary. The shuttle has" a'longitudinal cavity 4- to receive thebobbin 2. 'The shuttle is provided with opposite nose ends 5,

of which but one is shown, it beingunder stood that-the two ends of the shuttle are similar except that at one endjtensionfdevicesare '-prov ided,'while these tension de-. -v1ces a-reonntted from the other end of the shuttle.

Tension devices located at one end ofithe cavity in" the shuttle comprise plateon table 6, whichmay be conveniently of metal,

and at one end thefp'late is 'provided'with a post or leg 7 terminating in afoot '7? shaped toengagethe' bottom 'ofthe' cavity 4 and. v

having a slant or trend to'ward'theother end of the shuttle. The foot 7- is provided with an eye 8 of proper shape'to pass ascrewj9 and ,receive the head thereof. Extending from "oneside'of'the table 6 is an arm 10 so located and shaped as to lie against the adjacent inner face of oneside wallof the shuttle 1,' and this aim is secured to the shuttle by a screw 11 or in other appropriate manner.

The leg? is loc ated approximately mid;

way ofthe width of the table' 'and the lat ter is strengthened by an expanded-web 12 merging into the leg 7. Through the top of the table 6 are elongated slots 13 and under lying the table beneath the slots is an elastic tension member or finger 14' having spaced' ribs 15 partially entering theslots flThe finger 1.4. is madefast to the table at'the end 7 toward the leg 7 and between-the latter and- I the arm, 10, the arrangement being such that 1 the arm will give toward the J end remotei from the bobbin to a limited extent.

The face of the bobbin. adjacent to the The edges of the plate 6 presented toward arm 10 Qis recessed as shownat 16,,and in this recess there is seated atension plate .17

'- near the bottom end of the plate 17 and there merging into a slit 25 in turntermi-nating in an eye 26 also with rounded edges,

for the eye is designed to permit thepassage of the thread coming from the bobbin.

Whenthe'shuttle is placed in the loom the thread is properly adjusted by taking the free end of the thread, of which -a suflicient quantity is-drawn from the bobbin, and this thread isreadily passed about the plate 6,

first along the edge 21 thereof, then along the edge '22 and finally along the edge 23, which brings the thread *under the plate against the web 12 and overthe elastic-end or the tongue 14. The thread follows the 'web'Y12 toward the bobbin over the tongue 14, thence over the .ribs 15'to the rear ends thereof which are notched as shown at '27, thus preventing the return :movement of the -thr'e'ad. Then the thread .is directed along the edge 24 of the plate 17 until the slit 25 is reached, after which the threadwill pass easily into the eye 26 and be brought away 'froinf-the shuttle to the proper part of the loom. The thread passes from the bobbin about .the post 7, which l'atter has a cutaway portion or notoh 28 .guidingz'the thread so that it then lies along the web 12 in partial encircling relation to the post '7, thence over the finger 14 and the ribs 15 on the finger "through the notches 27, thence back -to the '1plate17-to and through the eye 26. In this manner the thread, which is applied byzprac- 'tioally one movement, is placed under ten- "'sion and risguid'ed at several points. There is the tension caused by the bobbin which i does not rotate "but from which the thread fguided about curved surfaces preventing maybe drawn. Then the portion of the 'thread'abou't "the post 7 adds to'the tension 0% "the thread, after which the passage of "the thread, in a somewhattortuous course 3in' front of the ribs '15 and then along the bath of the plate'17 and through'the eye '26, supplements the tension with the thread unduetensi'on sufiicien't'to injure the thread.
